W1L`LARD H. SMITH, oF NEW YORK, N. Y., AssIGNoR TOAFRANCIS c. cANTiNE, oF ORANGE, NEW JERSEY- Letters Potent No. 86,118, dated January 19, 1869; antedated January 6, 1869.

IMPROVEMENT IN LAMPS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Beit known that I, TILLARD H. SMITH, of the city, county, and State of New York, have invented a new and useful Improvement in insulating Buttons of Argand-Burners; and I do herebydeclare the following to be a full and correct description of the same, sufcaent to enable others skilled in the art to which my invention appert-ains, to fully understand and make the same, reference being had to the accompanying drawings, which make part of this specification, and in which Figure 1 is a side elevation ofthe improved burner;

Figure 2 is a top view of the same;

Figure 3 is a central vertical section of the same; and

Figure 4 is a det-ached View of a part ofthe same.

Like letters of reference indicate like parts in the several figures.

The nature of my invention consists in so insulating the button and button-rod of an argand-burner that the heat of the same cannot be communicated to thc bumer itself.

In the drawing- Amay represent an argand-burner, in which the rack-bar or button-rod, B, Which bea-rs the button C, is held, in suitable bearings, by means ofthe guides D.

The bearings, in which the rod B moves vertically, consist of an inner ring, a, and an outer one, B, loetween which a packing, c, is placed, which consists of a ring, of cork, or any other suitable non-conductor of heat.

E represents the toothed Wheel on the elevator-rod F, by means of which the rack-bar B and button C are elevated. Heat might be communicated through this wheel from the rack-bar to the burner. To prevent this, I construct the bearing oh the burner, through which this elevatorfrod passes, in the same manner as the bearings of the rack-bar B.

It is well known that, in burners of this kind, the button heats quickly, and intensely, which heat, being communicated through the burner to the oil, causes the saine to lill the burner, and, when the lamp is extinguished, a had smell to pervade the room, caused by the oil on the surface ofthe burner.

By my improvement the heat is not communicated to the oil, and thus the bad odor, lon extinguishing a lamp, prevented.

Having thus described my invention,

Vhat I claim as new therein, and desire to secure by Letters Patent, is-

Insulating the button and button-rod of argandburners, in the manner substantially as herein described.
